2022-3-4 · Biological clocks control circadian rhythms in plants and other eukaryotes. Many plant processes, such as transpiration and synthesis of certain enzymes, oscillate during the day. This is often in response to changes in light levels, temperature, and relative humidity that accompany the 24-hour cycle of day and night.
2019-3-25 · You should test each of the four enzymes separately (e.g. A only, B only, C only, D only), and also create two additional biological detergents by mixing enzymes together (e.g. A and B, or B and C). To predict which enzyme is which, test the performance of each enzyme-containing detergent on each of the stained fabrics.
